In 2002/2003 I saw a movie on TV that didn’t look like it had ever been on the big screen.  It was in color.  It was a psychological thriller.

From what I remember, it had a recurring theme of dripping water.  The main character was a woman who had a traumatic incident involving a man at a circus when she was a child.  (The following is a bit fuzzy in my mind):  I believe at the end, it’s revealed that she is fully grown and locked in the trunk of a car that has gone into the water.  The dripping water throughout the movie is invading her memories/dreams as the water fills the car.
